Sweaty Betty White Athlete Seamless Workout T-Shirt Top. A looser, more relaxed, and lighter feel compared to the classic Sweaty Betty Athlete Seamless t-shirt. Crew neckline with short sleeves and a seamless construction to prevent chafing. Features 4-way stretch, moisture-wicking/sweat-resistant properties, and quick-drying capabilities. Pit to pit the top is 20 inch (51 cm) across. Because it's lightweight it isn't totally opaque, so it does need something like a Sweaty Betty stamina bra underneath it for modesty.
